Never trust an exchange. Bittrex disabled my account and despite verifying and doing all the steps told after 3 months Im still waiting for them to enable my account access.
I think Bittrex is going through liquidity issues perhaps got hacked or loss heavily in trading so to maintain liquidity they are disabling random accounts to prevent getting busted.
I recommend to take your money out of exchanges specially bittrex and keep it in your own wallets.
I learnt the hard way!
